In the context of work in physics, what is the equation for calculating work done by a constant force aligned with the direction of motion?
The equation for calculating work done by a constant force aligned with the direction of motion is given by $W = F \cdot d$, where $W$ is the work done, $F$ is the force, and $d$ is the distance traveled.
What type of work does a force do when it has a component in the direction of the displacement of the point of application? Provide an example.
What type of work does a force do when it has a component in the direction of the displacement of the point of application? Provide an example.
When a force has a component in the direction of the displacement of the point of application, it does positive work. An example is the work done by the gravitational force on a falling ball, where the force and displacement are in the same direction.
When does a force do negative work? Give an example to illustrate your answer.
When does a force do negative work? Give an example to illustrate your answer.
A force does negative work when it has a component opposite to the direction of the displacement at the point of application. An example is the work done by the gravitational force on a ball thrown upwards, where the force and displacement are in opposite directions.
Explain the work done by the gravitational force on a ball as it falls towards the ground. Is the work positive or negative?
